I have struggled for a couple years with this trying to get some actual instructions on how to actually make it work - in case I needed it. Well, now I do and I'm no closer to accomplishing this than I was two years ago.
I have setup the completion criteria for a course as student must view.
I have set "allow" for course creator and teacher for the Moodle/Course:Mark Complete permission
I have set the completion requirements for the course to be marked complete by others to "Any" in the list which includes creator and teacher and have checked them both.
I have looked at the course completion block and course completion reports and still have the grayed out checkbox for "complete". I have never seen it other than in that state.
Can someone please run me through this as the documentation just isn't there that I can find. Please??
